How to fix SessionNotCreatedException: Unable to create new remote session when trying to run Firefox?

I have a Selenium server 4 with Chrome and Firefox. Chrome works fine but as I try to run Firefox it throws me an error:

org.openqa.selenium.SessionNotCreatedException: Unable to create new remote session. desired capabilities = Capabilities {acceptInsecureCerts: true, browserName: firefox, marionette: true}

The Java code for driver is here:

String browser = System.getProperty("browser");
browser = browser == null || browser.equals("") ? CHROME : browser.toLowerCase();

System.setProperty("webdriver.gecko.driver", "/home/tatrytec/custom-scripts/selenium-server/geckodriver");

Configuration.remote = HUB_URL;
Configuration.browser = browser;

FirefoxOptions options = new FirefoxOptions();
options.setCapability("marionette",true);
options.setHeadless(true);
WebDriver driver = new RemoteWebDriver(options);
WebDriverRunner.setWebDriver(driver);

Here is the Jenkins stack trace:

It seems something is wrong with permissions on the server. It says:

cannot start document portal: dial unix /run/user/0/bus: connect: permission denied

Have no idea what else should I set up to run.

This is common with firefox installed using snap you can uninstall snap version of firefox and install it with apt by

snap remove firefox

then

sudo apt-get install firefox
sudo apt-get install firefox-geckodriver
